This standby air conditioning operation can be carried out with 12 liters of fuel without any problems for 12 days in continuous operation. The stand-by air conditioning operation is performed until the user selects feel-good air conditioning just before starting to drive, which then cools the interior 78 to, for example, 18 ° C. The Wohlfühlrytmaschine is then carried out until the drive unit 94 is restarted.
